Hi,

I've found my system with memory almost full. I see

I think it's too much. But what do you think?

Definitely too much.

We've seen this behavior before and there is a ticket currently open for it (see http://tracker.ceph.com/issues/8036), as this increasing memory consumption will eventually trigger an OOM on machines with low amounts of RAM. However I haven't been able to reproduce it once to actually investigate what the problem might be.

Do you have any idea how you got here?

Also, could you please run

'ceph heap stats -m IP:PORT', with IP and PORT of that monitor, and send us back the result?
